it appears that run_with_callbacks_and_mocha does not catch Exception (or the Passthrough exceptions) like run_with_callbacks_and_testunit does.

That means any thrown Exception or Subclass of Exception kills the test run, and thus breaks our continuous build.

I'm not in the know about why run_with_callbacks_and_mocha is written this way but it looks like bug to me.
